      Hi,
      I can send a gcode for power on layer fans while the printing job has started?

      The layer fans are not starting she reach layer 1,when it's supposed to power on....

      And I force to power on in DWC... and don't power on...

      I would check if with gcode responds

          ; GCODE FAN
          M106 P0 S1 I0 T100 H1
          M106 P1 S0 I0 F500 H-1
          M106 P2 S0 I0 F500 H-1
      

      I have this in config. G, until now, I don't use layer fans, I print in Abs...

          @peirof The default part cooling fan is P0 but you have that set as a thermostatic fan to come on when Heater 1 reaches 100 deg C. So I guess you are using that as the hot end cooling fan yes?. You have P1 and P2 as non thermostatic fans so I guess you want to use these as your part cooling fans yes?

          If that is the case, then as @Veti says, you need to map those fans to your tool (or tools) by adding F1:2 to your M563 commands https://duet3d.dozuki.com/Wiki/Gcode#Section_M563_Define_or_remove_a_tool

            From https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_fans:

            Our intention is that in a 3D printer with a single print head, you use the Fan0 output for the print cooling fan and the Fan1 output for the heatsink fan. This is the easiest configuration to use because it's what the firmware expects by default.
